JOHN A. PANTON, OF QUINCY, MASSACHUSETTS.

LEATHER-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 313,231, dated March 3, 1885.

Application filed November 29, 1884.

To all whom it may concern.-

Be it known that I, JOHN A. PANTON, of Quincy, in the county of Norfolk and State of Massachusetts, have invented a new and Improved Leather Working and Scouring Machine, of which the following is a full, clear, and exact description.

My improvements relate to the Holmes- Fitzhenry scouring-machine, and have the ob ject to prevent the stones striking the table while the stock is being scoured, set, or worked.

The said improvements consist of the coinbinations of parts and their construction, substantially as hereinafter fully set forth and claimed.

Reference is to behad to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a side elevation of the carriage of a scouring-machine with the improvements, and Fig. 2 is a detail section on the linewxof Fig. 1.

The carriage A, suspended for movement on slidebar B, the tool carriers 0, spiral springs D, and oscillator E are of ordinary character. F F are two levers hung on the top of the carriage, and extending outward, and carrying on their outer ends the long sleeves G, that are upon the tool-rods H, between cushion I above the oscillator E and nuts K on the upper ends of rods, whereby the position of the tool-carrier can be adjusted as described in my patent aforesaid. The spiral springs D are con uected to screws L, that extend through holes in levers F, so that each lever is held down by its spiral spring. By thus independently supporting the two tool-carriers there is no possibility of the pressure of the stone at work being affected when the oscillator trips up the back stone, because there is no connection of the moving parts at the two ends of the carriage. Neither is the reach of either tool-rod affected by the opposite lever. The result is an even stroke with even pressure, and the danger of wearing hollows in the table is prevented.

The sleeves G determine accurately the position of the cushion on the tool-rods,and the adjustment is not thrown out byimperfect working of the lever, and as the oscillator does not (No model.)

affect the position of the stones, except to trip them up on the back motion, the cushions may be allowed to wear considerably without adjustment being required.

The levers F are allowed to rest on the slidemetal, and riveted upon the lower portion, 1),"

of hard vulcanized fiber. At each end of the part a is a shoulder, these shoulders receiving the top of the carriage between them and coming up at each side, so as to retain the gibs in place. The Vulcanized fiber for this purpose is advantageous, as it does not wear so fast as composition nor heat as Wood does.

Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is-

1. In a leather working and scouring machine, the carriage with the tool-carriers con nected thereto and to rodspassed through an oscillator, through cushions resting upon said oscillator, and through sleeves having levers,

the inner or opposite ends of said levers being pivoted to the carriage, in combination with the two-part gib, having one part provided with a shoulder at each end to receive between them the top of said carriage, the other part of said gib being composed of hard Vulcanized fiber, and secured to the aforesaid part of gib, substantially as and for the purpose set forth. y

2. In a leather working and scouring machine, the combination, with the carriage, of the twopart gib, having one part provided with a shoulder at each end to receive between them the top of said carriage, the other part of said gib being composed of hard vulcanized fiber, and secured to the aforesaid part of gib, substantially as and for the purpose set forth.
